The butterfly valve is another type of valve that operates with a 90-degree rotational movement and features a control function. The rotational movement of the circular or rectangular discs allows for stopping, regulating, and starting the flow within piping systems. Due to the quarter-turn operation of the actuator, the flow adjustment speed with this valve is high. Butterfly valves are used in systems where frequent on/off operation of the flow is not required. These valves are suitable for controlling the flow of various gases, liquids, and slurry in different industries, even under high pressure and temperature conditions.
